Tunable diode laser (TDL) sensor-based trace moisture analyser, designed for measuring diverse gas mixtures in specialty gas blending applications. Using intelligent integrated software, this device includes a database of 17 standard background gases - with blends of up to 8 gases - providing an adaptable solution for diverse application needs; 30 custom gas mixtures can be predefined directly via the front panel interface. A robust hardware / software design enables the SGMax to be moved easily from port to port, virtually eliminating dry down times often associated with these applications.

Servomex’s leading-edge TDL technology has been engineered to deliver a broad measurement range of 0-100ppm, with an incredible low 5ppb LDL - the lowest available without using a pump. This device is also highly affordable over product life, through the use of ultra- stable, zero drift sensing technology that helps to extend calibration periods and reduce ongoing maintenance needs.

Flexible
  • Trace level Tunable Diode Laser (TDL) sensing provides high stability measurements through minimal moisture contact with optical elements
  • Broad detection range: 0-100ppm
  • Gas blend storage, recall and measurement data display via integrated LCD interface
Easy to use
  • Pure/specialty gas blend mixtures: database of 17 standard background gases and blends of up to 8 gases. Pre-define 30 gas mixture templates or create customized blends
  • Display shows real-time analysis and reference spectrum for increased user confidence
